Product details
Overview
SST26VF016-80-5I-QAE from Microchip Technology is a 16 Mbit Serial Quad I/O™ (SQI™) flash memory IC designed for high-speed, low-pin-count code storage in embedded systems. It operates at 2.7–3.6 V, supports 80 MHz clock frequency, delivers 320 Mbit/s sustained data rate in SQI mode, and features 100,000 program/erase cycles with >100-year data retention. It is used in GPS modules, Bluetooth headsets, and optical disk drives requiring XIP-capable nonvolatile memory.
For engineers reviewing the SST26VF016-80-5I-QAE datasheet, SST26VF016-80-5I-QAE pinout, SST26VF016-80-5I-QAE application, or SST26VF016-80-5I-QAE equivalent, key selection considerations include its 80 MHz SQI interface, 256-byte page programming, flexible block protection scheme, industrial temperature range (–40°C to +85°C), and dual-package availability (WSON-8 and SOIC-8).
Technical Context
The SST26VF016-80-5I-QAE implements a 4-bit multiplexed serial interface supporting both legacy SPI (Mode 0/3) and proprietary SQI protocol, enabling quad-data-rate transfers without additional pins. Its SuperFlash® technology uses split-gate cells and thick-oxide tunneling for enhanced endurance and lower energy per erase/program cycle.
It integrates a 48-bit Block-Protection Register with independent write/read lock control for eight 8 KByte parameter blocks and write-lock only for 32/64 KByte overlay blocks. The device also includes a 256-bit Security ID (64-bit factory-unique + 192-bit user-programmable) with lockout capability and supports write-suspend/resume for concurrent access across memory regions.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Winbond W25Q16JVSIQ | 16 Mbit, 133 MHz QPI/DTR capable, but lacks Index Jump and Security ID features | Better raw speed in QPI mode; less suitable for secure boot or low-overhead relative addressing | Choose for maximum throughput in non-security-critical, high-clock-rate designs |
| Cypress S25FL116K0XMFI011 | 16 Mbit, 104 MHz, supports Octal DTR; no SQI mode or Security ID; different block protection granularity | Higher bandwidth in Octal mode; lacks SST's write-suspend and parameter overlay block architecture | Prefer when migrating to Cypress-compatible toolchains or requiring octal interface compatibility |
Compared with W25Q16JVSIQ and S25FL116K0XMFI011, the SST26VF016-80-5I-QAE offers unique advantages in deterministic low-overhead addressing (Index Jump), integrated security (OTP SecID), and concurrent operation (write-suspend), making it optimal for resource-constrained, safety-aware embedded systems where firmware integrity and real-time responsiveness are prioritized over peak bandwidth alone.

FAQ
What interface protocols does the SST26VF016-80-5I-QAE support?
The SST26VF016-80-5I-QAE supports both standard SPI (Mode 0 and Mode 3) and proprietary Serial Quad I/O™ (SQI™) protocols. At power-up, it defaults to SPI mode for backward compatibility; the EQIO command (38H) enables 4-bit multiplexed SQI operation. High-Speed Read (0BH) works in both modes, while full SQI bandwidth (320 Mbit/s) is only achievable in SQI mode at 80 MHz.
Does the SST26VF016-80-5I-QAE support execute-in-place (XIP) operation?
Yes, the SST26VF016-80-5I-QAE supports true XIP operation due to its 80 MHz SQI interface and low-latency read architecture. It enables direct CPU instruction fetch from flash without SRAM shadowing, reducing system memory footprint and power consumption - a key advantage confirmed in the device's product description and timing specifications.
What is the memory organization of the SST26VF016-80-5I-QAE?
The SST26VF016-80-5I-QAE contains 16 Mbit (2 MByte) of flash memory organized into uniform 4 KByte erasable sectors, eight 8 KByte parameter overlay blocks, two 32 KByte overlay blocks, and thirty 64 KByte overlay blocks. This hierarchical structure supports flexible firmware partitioning, secure boot code isolation, and parameter storage with independent protection granularity.
How does the Security ID feature work on the SST26VF016-80-5I-QAE?
The SST26VF016-80-5I-QAE includes a 256-bit Security ID: 64 bits factory-programmed with a unique identifier (non-erasable, non-modifiable), and 192 bits user-programmable. Programming is done via the Program SID (A5H) command; once locked using Lockout SID (85H), no further writes are possible. This provides hardware-rooted device identity for secure authentication and anti-cloning.
Can the SST26VF016-80-5I-QAE be used in industrial temperature environments?
Yes, the SST26VF016-80-5I-QAE is rated for industrial temperature operation from –40°C to +85°C, as explicitly stated in the "Temperature Range" section of DS-25017A. Its SuperFlash® technology ensures specified endurance (100,000 cycles) and data retention (>100 years) across this full range, qualifying it for deployment in harsh-environment industrial HMIs and automotive infotainment systems.
